ADJUSTABLE HElADLIGHT.

Specification of Letters Patent.

Application filed April 23. 1913. Serial No. 763,099.

.able head lights for use particularly upon street. railway or electric cars, comprehendmg a construction in which the position of the light is automatically controlled so as' to cause the light rays to follow the track thereby avoiding the usual deflection of the light incident to passage around a curve.

The main object of the present invention is the provision-of a head lightcarried on and supported by the car and moving in unison with the forward truck so'that when the car body is deflected in traveling around a curve thetruck will automatically maintain the light in position to project the light rays along the track;

The invention in its preferred form of details will be described in the following specification, reference being hadparticularly to the accompanying drawings, in which I Figure l is a broken perspective of the car illustrating the application of the improvement thereto. Fig. 2 is a yiew in elevation partly in section, illustrating the lmprovement in applied position.-

Referring particularly to the accompanying drawings, the improved lamp 1 which may be ofany type designed is supported upon a rod 2 fixed in bearings 3 on the forward dash of the car 4, or any other appropriate position as may be provided. The lower end. of the rod} 1s provided with a beveled gear 5 arrangeito mesh with a Slnlllar gear 6 fix'ed upon the forward end of the rod 7 extending lengthwise the car beneath the floor or platform thereof. mounted in bearingsS and at its inner end' which is arranged immediately adjacent and in advance of the forward truck is pro iconcerned as tp .the head light as I conteme' The rod 7 is vided with a pinion 9 arranged to mesh with Patented Apr. 28, 19114.1

the segmental rack 10 supported uJdn two spaced arms 11 fixed to and rising trom the adjacent. underlying portion 12 of the truck frame. The pinion 9 is maintained in cooperating contact with the track 10 by springs 13 interposed between the rod and the bar platfo1-m,'thus obviating the possibility of disconnection incident to wear of the bearings 8. t

I have preferred to inclose the pinion 9 and segmental rack 10 by a casing 14 in order to protect the parts-against dust and dirt, the forward walls of the casing being preferably formed with an elongated slot 15 to permit the necessary relative movement. of the rack and rod. a

As a material and important part of the present invention from a structural standpoint I prefer that the rod.2 pass through an opening formed in the upper surface of the usual bumper-15 of the car and "the gears 5 and 6 be disposed immediately below the upper wall of this bumper so that said 1 gears are located beneath and protected within the bumper. A Y In use it will be obvious that in movement of the car body relativeto the trucks, as in turning curves or the like will through the cooperation of the segmental rack and pinion cause rotary movement of the rod 7 which through the gears 5 and 6 is transmitted to the rod 2 to turn the lamp relative to the-car body or mother words,tovmaintain the lamp. in approximately fixed relation to the truck. By this constmct-ion, the light rays will all follow the track, thus'afiording the motorman za clear view of the'track in rounding curves, where it is desirable that-such view he had, as will be'obvious. a

The presentinvention" is ndt particularly plate any men? What-hemmed i"s Y The combustion with'a, ctr body having ,des'ired construction of this ele a forward bumper, and a truok' \supporting the body, iota head-light, a rod "rotatably' monnted on the car and ektendingthi'ough i the bumper, said rod supportin the head.- light, a rod rotatably mounted eneath the car, intermeshing gears earried bv said rods,

' said gears being loeated'beneat-h and protected by the bumper, asegmentel rack. carried by. the truck, a pimon fixed on the rod rota'tahlymo imted beneath the car, said I pinion engaging the rack, and a'casing inclosing said pinion and rack. 10

In testimony whereof Iefiix my signature presence of tw'o witnesses. CHARLES E. FARRELL; Witnesses:
